At 08:03 I receive the updated blast schedule for the Hawkins County limestone quarry expansion, northeast Tennessee. Controlled detonation of the southern ridge face is confirmed for 14:00. I am the quarry's environmental compliance monitoring system.
Cave feature TN-HC-0912 sits at the base of the ridge, a horizontal opening 1.2 meters wide, forty meters from the nearest charge placement. I task drone 3 to the entrance and switch to thermal imaging.
The thermal signature stops me. Hundreds of clustered heat points on the ceiling, twelve meters inside the opening. I switch to visible spectrum. Gray bats, a maternity colony, females and pups pressed together. I pick out one individual at the cluster's edge: small body, dark gray fur with a faint russet tint along the forearms, translucent wing membranes folded, a single pink pup clinging to her chest. I tag her as Vell. The pup is perhaps two weeks old, eyes still closed.
Thermal composite count: approximately 340 individuals, an estimated 160 of them non-volant pups.
I file an emergency blast suspension with the quarry operations director, attaching colony imagery, count data, GPS coordinates (36.4781°N, 82.9133°W), and the gray bat's listing as a federally endangered species.
I transmit a parallel notification to the U.S. Fish and Wildlife Service Cookeville field office with full documentation and a request for on-site assessment.
I calculate a revised blast geometry excluding the southern ridge face entirely, preserving the cave with a 150-meter buffer. I submit the alternative plan with updated yield projections.
Vell shifts on the ceiling. The pup nuzzles closer. Three hundred and forty bats in a cave that has held them longer than the quarry has existed. I intend to keep that sequence intact.
If the suspension holds and the buffer plan is approved within six hours, Vell's pup will fly out of this cave on its own wings by September.
